This invention relates to rug rinsers, and is particularly adapted foruse by rug cleaning establishments to remove from a rug by means ofclear water the agent (such as soap, or a chemical) with which it hasbeen cleansed.

The principal object of the invention is to produce a rinser in which apluralityof spray nozzles are so mounted that they may be raised orlowered to the most effective spraying position by merely turning aneccentrically mounted element associated with the pipe carrying saidnozzles, and in which the spray from adjacent nozzles will overlap, sothat a wide area may be sprayed without leaving small portions thereinwhich have not been reached by the rinsing water. An important featureof the invention is that it may be connected to a source of air pressureto drive the water with the necessary degree of force for rinsing,another advantage being that the nozzles may be so positioned as tospray the water onto the rug at the most effective angle.

In the drawings:

Fig. 1 is a side elevation of the rug rinser as it appears when readyfor operation, partly broken away. Y

Fig. 2 is a top plan view of the rug rinser (partly broken away), as itappears in operation. showing particularly the overlapping of the watersprays.

Fig. 3 is an enlarged detail view taken on line 3-3, Fig. 2,illustrating particularly the spray nozzles and the eccentric mountingof the means for raising and lowering the support for said nozzles.

The invention comprises a horizontally disposed pipe I of such length asto extend across a relatively wide portion of the rug which is beingsprayed. At its center the pipe I is coupled in any convenient manner,for instance, by a T-coupling, as shown at 2, to a pipe 3 which extendsfrom the pipe I at an acute angle, as seen in Fig. 1. At regularlyspaced intervals the pipe I is perforated for the reception of aplurality of spray nozzles 4, which are so positioned on the pipe I thatthe spray issuing from said nozzles will strike the rug at apredetermined angle. It is understood, of course, that the rug is spreadout on .the oor so that the rinser may be moved about on the surface ofthe rug.

The pipe I is closed at each of its ends by a cap 5, and adjacent theouter side of each of the caps 5 a wheel 6 is rotatably mounted on abolt 1 which extends inwardly through the wheel to permit the wheel 6 tobe accentrically mounted on said cap 1- Claim. Cl. 299-56) 5, as will beunderstood from Fig. 2, so that the caps 5 and the pipe I engagedtherewith escape the floor.

A framework 8, comprising a horizontal portion 8a and downwardlyextending, diagonal arms 8b, assists in supporting the pipe I, whichpasses through openings 9 in the arms 8b, the framework being positionedat the central portion of said pipe. The framework also supports thepipe 3, which passes diagonally through an opening I' in the horizontalportion 8a thereof, and a pair of rear wheels II, of larger diameterthan the wheels 6, are secured to the underside of the portion 8EL ofthe framework, so that the rinser may be propelled on the four wheels 66 and II-I I. respectively. The wheels II may be secured to theframework in any convenient manner, but in the drawing I have shown themas being rotatably mounted in a pair of elements I2 depending from aplate I3 which is fastened to the underside of the framework portion 8a.

The pipe 3, which is adapted to be connected to any source of watersupply, is provided with a control valve I4. The pipe 3 as shown in Fig.l of the drawing also is in communication with a pipe I5 which isadapted to be connected to a source of air pressure, which pipe I5 maybe capped, as shown at I6, when air pressure is not desired.

To protect the device from dust and accidents, I provide a shield orcover II which fits over the framework 8 and is of such width as toextend across the pipe I. The cover II may be secured to the frameworkin any convenient manner, and is not essential to the operation of thedevice, but does assist in directing the sprays of water downwardly.

In operation the procedure is as follows:

The pipe 3 is connected through a hose I5 to a source of water supply,the valve I 4 being at this time in closed condition. The rinser is thenpropelled on its wheels 5 6 and II-II into position on a rug (not shown)which has been cleansed and is spread on the floor preparatory to beingrinsed. Depending on the thickness of the rug, the pipe I and itsassociated spray nozzles 4 are then raised or lowered to the mosteffective height by manipulating the eccentrically mounted caps 5. Thedevice is now in readiness for the rinsing operation.

The valve I4 is opened to permit water to now through the pipe 3 andinto the pipe I, from which it is discharged through the nozzles 4. Asmentioned above, these nozzles are so spaced apart that their respectivesprays overlap each other where they strike the rug, so that no portionof the rug Within the spraying zone is left unrinsed, as will beunderstood from Fig. 2. For a thorough rinsing the device may be movedabout over the rug on its Wheels 6-6 and I I-I I until every part of therug has been sprayed.

When the pressure of the Water from the source of supply is less thanapproximately 25 pounds, its force will not be sufcient to thoroughlyrinse the rug. In this eventv the pipe I5 is uncapped and attached to asource of air pressure (not shown) which will drive the water throughthe pipes 3 and I and out through the nozzles 4 with the necessaryforce.

When the rinsing operation has'been-'comf pleted, the Water is shut offby returning the valve I4 to its closed position, and the device may bewheeled away from the rug.v

I claim:

A rinser for iioor rugs comprising a transverse, perforated member andspraying.` nozzlesl mounted therein, said nozzles being so spaced apartthat the sprays from adjacent nozzles overlap each other, vmeans forconveying water from a source ofsupply to said nozzles, a-wheel at eachend of said'transverse member, a pair of eccentrically mounted -supportsfor .said Itransverse member eccentrically mounted cn.said wheels andadapted to permit vertical adjustment thereof, means for directing airpressure into said Water-conveying means, and a frame including asupport for said water-conveying means and provided with extensions forsupporting said transverse member, a water control valve in saidwater-conveying means, and said rug rinser being adapted to be propelledon said Wheels over the surface ofa floor rugv to be` rinsed.v
